2 Claims. (01. 70-113.) s

invention relates to combination padlooks and has for the object, the provision of a device of the above stated character which will be burglar-proof, easy to lock and unlock when having knowledge of the proper combina' tion, and is so constructed that the combination may be easily and quickly changed without substitution of new parts and also permits a large number of different combinations to be had.

With this and other objects in view, this invention consists in certain novel features of con struction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which 7 Figure l side elevation illustrating a cornbination padlock constructed in accordance with my invention. v Figure 2 is a sectional view taken on the line 2-2 of Figure l.

Figure lz-isa side elevation illustrating the application of an element to the lock for permitting the combination to be easily actuated when the figures or char cters cannot be. easilyread. Figure 13 is a perspective view illustrating the element. r V 7 Referring in detail to drawings,-the nu.- nieral 1 indicates a body of cylindrical shape having adjacent each end shackle socket 2 to receive the e; 'is of a substantially ll-shaped shackle 3. Portions of thed gs of the shackle are reduced as-shown in get 4 .to enter: the sockets 2 and providing annular shoulders a on the shackle-toabut the outer wall of the body to lin'i'it the inward movement of the reduced portion of the legs into the sockets 2. One or the leg portions is shorter than the other leg portion and adjacent its free end is provided with n on the line view illustrating one of a notch 5 havinga bevelled wall new abrupt or ri htangle wall relative thereto sothat when the locking key or element 6 is arranged within the, notch 5 the outward movementv of the shackle is prevented. The other leg' of the shackle is provided with a notch 7 corresponding in shape to the notch 5 and also adapted to receive the key or locking element 6, thus. it will be seen that both ends of the shackle may be locked within the body. The last named leg portion of the shackle is provided with a reduced portion 8 having a bevelled wall 9 at one end and an abrupt or rightangle'wall 10 at theopposite end. A spring pressed pin 11 is carried by the body 1 and fits withinlthe recess 8 and is adapted to allow the inward movement of the shackle relative to the body but which will limit the outward movement of the shackle when engaged with the shoulder ll to'prcvent complete separation of the shackle from the body. The right angle or abrupt shoulder 10 is located adjacent the end of the respective leg portion of the shackle and has a slo 12 extending therethrough for the purpose of receiving the spring pressed .pin 11, and thereby allowing the passage of the said end of the shackle by the plunger 11 when desiringto disconnect the shackle entirely from the body ll. It is to be understood'that the shackle rnustbe turned into a proper position to bring the slot 12 in alignment with the spring pressed keyeither when connecting or disconnecting the shackle entirely from the body 1.

The'body 1 consists of end members 13 having sockets 14 formed in their opposing faces to receive a connecting element 15 and the latter is .wardly through the ends'of the connecting ele- 1n? nent l5 and the key groove 19 slidably receives the key or locking element 6 which is provided on one edge with relatively spaced teeth 28 that project outwardly of the key groove 19. The opposite edge of the key 6 from the teeth 2Q and v adjacent one. end is provided with a notch 21 arranged oppositelto the notch2land uponvthe same edge of the key 6 asthe teeth 29 is a projection. 22 .adapted to slide within? a chamber 23 formed in one of the end members 13 O]. t e body and is in communication with the recess of the respective end member. A plunger 24 is slidable in a chamber 23 and through an opening in the end of the respective end member for the purpose of permitting a person to manually slide to form relatively spaced ends 30.

the plunger in one direction and to position the key or locking element 6 within the notches 5 and 7 of the shackle for the purpose of locking the shackle against relative movement to the body. Figure 2 shows the key or locking element positioned to secure the shackle to the body against relative movement thereto.

Bearing portions 25 are formed on the opposing faces of the end members 13 of the body and engage the connecting element 15 as shown in Figure 2. Annular spacing elements 26 are mounted on the connecting element 15 and which are provided with oppositely disposed lugs 27 fitting within the grooves 18 of the connecting element to prevent said spacing elements from having rotation relative to the connecting element. The spacing elements 26 are provided with notches 28 aligningwith the key groove 19 for the purpose of permitting the key to have sliding movement endwise relative to the connecting-element. Annular locking elements 29 are mounted on the connecting element 15 between the spacing elements 26 and are cut or severed The ends 30 being relatively spaced provide passages which when aligned with the key groove 19 permit the key to have endwise movement relative to the connecting element 15.

A series of annular operating elements 31 are rotatably mounted on the spacing elements 26 between the end members 13 of the body with the locking elements 29 confined therein'and having frictional contact therewith. The frictional contact of the locking elements 29 with the operating elements 31 is sufficient to cause. the locking elements to rotate on the connecting element 15 by the rotation of the operating elements and the latter are provided with a series of characters as shown in Figure 1 adapted to cooperate with a series of characters on the end members 13. The operating elements 31 are provided with finger pieces 32 whereby a person can conveniently rotate the various operating elements relative to each otherfor aligning certain characters of a combination and with the characters on the end members of the body.

A person familiarwith the proper combination of the lockrotates the various operating elements 31 until the characters of the combination align which positions the passages of the locking elements in alignment with the key groove 19 of the connecting element 15 and on tilting the locking endwise, the key gravitates into a position to become disengaged from the notches 5 and 7 of the shackle, thus allowing the shackle to be moved outwardly relative tothe body and freeing one end of the shackle that the same may be removed and replaced in a keeper. To lock the device, the plunger 24 is moved inwardly positioning the key as shown in Figure 2 and by v turning several of the operating, elements 31, the

passages of the locking elements 29 will be moved out of registration with the groove 19 and will lie between the teeth 20 of the key preventing endwise movement of the key.

straight passage is established to the chamber 23 from the passage 34 whereby a small instrument or wire may be inserted for the purpose of imparting endwise movement to the key.

When it is desired to change the combination, it is only necessary to move the operating ele ments 31 relative to the operating elements 29 and this can be easily accomplished when the locking elements 29 are so positioned that their ends 30 abut the teeth 20 on the locking element or key 6.

An element 36 is provided for aiding a person in operating the combination of the lock at night time or when the characters on the lock cannot be easily read and is adapted to be positioned against the body of the lock with one edge in engagement with the shackle 3 while the opposite edge is shaped to cause the combination of the lock to be actuated properly when the finger pieces or pins 32 are brought into engagement therewith as shown in Figure 12. a While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is:
